Wearable during-walking arm exercise device

ABSTRACT

The present invention relates to a device for enabling a natural arm exercise during everyday walking. More specifically, the present invention relates to a wearable during-walking arm exercise device comprising: webbing belts extending from the user&#39;s front chest part and through the shoulder parts, and crossing each other in an X-shape on the user&#39;s back, thereby holding the entire device; one elastic string or multiple elastic strings coupled to the front and rear of the webbing belts, the elastic strings having elasticity such that, according to relaxation and contraction movements following forward/backward movements of arms, backside muscles of upper arms undergo exercise; and a handle fastened to the elastic strings so as to tension the elastic strings. Additionally, the wearable during-walking arm exercise device comprises a waist string having elasticity, the waist string being connected to the lower portion of the handle for muscle movements of front portions of the upper arms (biceps contracts). The elastic strings and the waist string are connected on the upper and lower sides of the handle such that, not only when arms are moved backwards (extension) as a result of walking, but also when the arms are moved forwards (flexion), both front and rear muscles of the upper arms (biceps brachii and triceps brachii) are tensioned and are thus exercised, thereby maximizing the merits of exercise.

TECHNICAL FIELD

The present invention relates to a piece of gear that enables naturalarm exercise while walking and, more specifically, to a wearable armexerciser usable for walking, including webbing belts passing from auser's chest through the user's shoulders and crossed in an X shape tofasten the overall wearable arm exerciser, one or more elastic stringscoupled, in front or behind, to the webbing belts and producing anexercise effect in the rear muscles of the upper arm according tocontractions and relaxations by the moving-forth-and-back of the arm,and handles coupled with the elastic strings to produce tension in theelastic strings, and further including a waist string, for exercisingbiceps, which is elastic and connected to lower parts of the handles,wherein both biceps and triceps are tensioned to produce an exerciseeffect not only when the user moves his arm back while walking (i.e.,arm extension) but also when the user moves his arm ahead (i.e., armflexion), thereby maximizing the exercise effect.

BACKGROUND ART

Generally, walking is enjoyed by many people who desire to stay healthy,requires no separate tool, and may be practiced anywhere easily androutinely.

Meanwhile, human beings may walk upright, unlike other quadrupedalanimals, do not involve any separate exercise activity except forshaking their arms while walking.

Such an imbalance in exercise between arms and legs may result inmuscular dystrophy in arms or cause degenerative disease such as frozenshoulder.

For balanced development between arms and legs, various walkingexercises are being attempted, such as quadrupedal walking, powerwalking, which is the act of walking with an exaggerated arm swing,walking with dumbbells in hands, and Nordic pole walking which is apole-in-hand form of walking, recently widely practiced nationwide orworldwide.

As compared with indoor cycling that uses 30% to 40% of the body musclesand jogging or walking that uses 50% to 60% of the muscles, Nordic polewalking has been reported to use 90% or more of the body muscles.

In contrast, Nordic pole walking, despite its superior exercise effects,are known to have many drawbacks in light of portability, indoorusability, intensity control, wrist shocks, fast running, usability onpavement, reduction in leg exercise, lack of various exercise programs,usability on treadmill, and exercise effect of biceps brachii.

Power walking is the way in which one walks fast while moving her armsup and back, with her arms bent at a 90-degree angle, so as to increasethe exercise effect. Power walking may not obtain the relaxation effectof the upper arms as Nordic pole walking because the elbow joints arenot stretched out. On the other hand, to maximize the effect of powerwalking, a separate auxiliary device is sometimes used.

Among such assistant tools, the one disclosed in Korean Utility ModelApplication No. 20-1982-0000736, titled “body exerciser,” enables wholebody exercise including arms and legs. However, all of the componentsare provided in a fixed type, and the device with tensioning springs mayproduce tension only ahead of the body, i.e., incapable of producingtension both forward and backward of the body, cannot be worn insideclothes, and lacks adjustment of exercise strength although it isrequired depending on the user's body capability and degree of fatigue.

Korean Patent Application Publication No. 10-2009-0124898 discloses an“assembled and disassembled band exerciser” which includes a fasteningbelt worn and fastened to a user's body and a band connected to thefastening belt and allows the user to do body exercise on his certainpart or whole body. However, it fails to apply tension to upper andlower muscles of the walker's arms. Korean Patent No. 10-0660636discloses a “whole body exerciser” by which the user may enjoy wholebody exercise by simply moving with the exerciser worn on the body.However, the exerciser cannot simultaneously distribute tension producedby a force that the user applies to the handle to the front and rear ofthe user's body and, thus, its exercise effect is degraded. KoreanPatent No. 10-1316428 discloses a “power walking assister” that puts aresistance to the user's arms which repetitively swing forward andbackward while walking quickly to increase the load of exercise andmaximize exercise effects. However, the assister is structured with amain body and elastic bands, which are provided separately, and isrequired to use a separate instrument installed on the user's back toadjust tension and the length of the elastic bands, thus unable toadjust the strength of exercise with the assister worn. Further, theconnecting structure of the left and right elastic bands on the back isseparated into a left and right part due to eccentricity so that whenone of the bands is pulled out, the other band cannot receive tension.Moreover, its feature of the two, front and rear, bands being requiredto simultaneously be pulled forward and backward results in incapabilityof evenly delivering tension to the arms while the arms swing forwardand backward. Further, the conventional exerciser, by its eccentricstructure, may be overall pushed forward when the band is pulledforward.

Unlike its goals to stretch the elbow joints back as much as possible asNordic pole walking while simultaneously generating the same amount oftension to the front and rear elastic strings, such exerciser generatestension only to the front string.

BEST MODE TO PRACTICE THE INVENTION

Hereinafter, preferred embodiments of the present invention aredescribed with reference to the accompanying drawings to be easilypracticed by one of ordinary skill in the art.

As shown in FIGS. 1 to 8, the present invention relates to a wearablearm exerciser 100 useable while walking, which enables natural movementof both arms and legs while walking upright, and the wearable armexerciser 100 basically includes

weaving belts 110 coupled with a fastening means 111 to stably fastenthe structure to a user's body to start from the user's chest, passthrough the user's shoulders and cross each other in an X shape,

a pair of elastic strings 120 coupled with first connecting rings 113and second connecting rings 114, which are connected to the webbingbelts 110 on the user's chest and back, through first connecting means121 and the second connecting means 122, respectively, while passingupper and lower parts of the shoulders, formed of one or more elasticwires, and forming closed loops with the webbing belts 110, and

an anti-friction device 150 mounted at lower parts of the pair ofelastic strings 120, having a circular arc shape to allow the elasticstrings 120 to slide according to movement of a handle to therebyprevent friction, positioning the handle at the lowest point of theelastic strings 120, and minimizing the abrasion of the elastic strings120, and

the handle 130 coupled to the anti-friction device 150 and gripped bythe user. When moving her arm backward (e.g., extending) while walking,the user pulls the handle 130 to stretch the elastic strings 120 andcontract the triceps brachii, and extend the elbow joint.

The wearable arm exerciser 100 further includes a waist string 140connected, via waist couplers 141, to third connecting rings 132 locatedopposite the handle couplers 131 with respect to the (pair of) handles130 to exercise the biceps brachii. At this time, the waist string 140is a long elastic string with both ends connected with the waistcouplers 141 to be coupled with the handles 130. As shown in FIGS. 1 to7, the handle couplers 131 and the waist couplers 141 produce a gap forinsertion when pressed, for coupling and decoupling, by the user to movetheir part and, when the pressure is removed, the part is moved back toits original position to prevent the inserted ring from escaping off.The handle couplers 131 and the waist couplers 141 may have any otherconfigurations for coupling or decoupling. The same is true for thefirst connecting means 121 and the second connecting means 122 describedbelow.

The elastic strings 120 and the handles 130 of the present invention areused in both hands. Thus, two elastic strings 120 and two handles 130,one on one side of the chest and the other on the other side of thechest, are installed.

The shoulder joint consists of three bones, i.e., clavicle, scapula, andhumerus and their related muscles, ligaments, and tendons. Shoulderjoint means a joint where the clavicle and the humerus meet together, ina narrow meaning, and all joints which are formed as the three bones, ina broad meaning. When a problem with the shoulder joint arises, all ofthe user's activities which are routinely done, such as washing orbathing, are limited.

Thus, according to the present invention, there is provided a wearablearm exerciser 100 usable while walking in which, as the user moves hisarms while walking, the elastic strings 120 produce tension that is thentransferred to muscles around the shoulders and repetitive extension andflexion of the arms leads to contraction and relaxation of thearound-shoulder muscles, reinforcing muscular flexibility, promptingbody fluid circulation, allowing for recovery of the mobility ofshoulder joint, preventing shoulder disease, and relieving pain.

The webbing belts 110 are formed of straps that are non-extendableagainst strong impacts and that, starting from the user's chest, passthe user's shoulders and cross each other in an X shape. The webbingbelts 110 are connected to the elastic strings 120, with the X-shapedcrossing of the belts facing the users back, to be worn on the user'sshoulders.

When the user pulls the detachable left and right handles 130, which arecoupled to the elastic strings 120 connected up and down to the webbingbelts 110 to form closed loops, after wearing the webbing belts 110, theelastic strings 120 may extend in the direction when the user's armsmove and remain in tension.

The webbing belts 110 have the fastening means 111 to stably fasten thestructure to the users body to be crossed in an X shape on the user'sback. The fastening means 111 have fastening holes spaced apart in threeor four directions, to allow the webbing belts 110 to be inserted,crossed, thereto.

The fastening means 111 may be distinctively provided for men or women.The fastening means 111 may be polygonal in shape when used for men,according to the first embodiment of the present invention as shown inFIGS. 1 to 4 and be circular in shape when used for women, according toa second embodiment of the present invention as shown in FIG. 5. Theabove-described shape of the fastening means 111 depending on whether itis used for en or women is merely an embodiment and the fastening means111 may be produced in other various shapes.

Where formed in three directions, the fastening holes may include afirst fastening hole, a second fastening hole, and a third fasteninghole. Where formed in four directions, according to the first and secondembodiments, as shown in FIGS. 3 and 5, the fastening holes may includea first fastening hole 111 a, a second fastening hole 111 b, a thirdfastening hole 111 c, and a fourth fastening hole 111 d.

When provided for men's use, the fastening means 111 may have an upperside wider than a lower side to allow the webbing belts 110 to becoupled in a broader area and thus stably fastened for male adults withbroad shoulders.

When provided for women's use, the fastening means 111 which is circularin shape has a first fastening hole 111 a, a second fastening hole 111b, a third fastening hole 111 c, and a fourth fastening hole 111 d whichhave the same shape and project in four directions.

Coupling means 112 each of which is formed by a female buckle member anda male buckle member which are cable of length adjustment and couplingand decoupling of the webbing belts 110 are provided to the webbingbelts 110 to allow the user to perform length adjustment and couplingand decoupling even without taking off the wearable arm exerciser 110already worn.

The coupling means 112 are placed on the user's chest near the shoulderswhen the user wears the wearable arm exerciser 100.

Thus, the user may easily adjust length after wearing the wearable armexerciser 100 of the present invention.

The coupling means 112 are provided to allow for length adjustment andare formed of a female coupling member at one side thereof a malecoupling member at an opposite side thereof to, when coupled together,enable coupling of the webbing belts 110 and, when decoupled from eachother, allow the wearable arm exerciser 100 from being removed theuser's body.

The fastening means 111 formed as a clip to fasten the webbing belts 110crossed in an X shape on the user's back is provided at the webbingbelts 110, keeping the webbing belts 110 separated left to right.

The first connecting means 121 and the second connecting means 122 areprovided at the first connecting rings 113 and the second connectingrings 114 which are provided at both ends of the webbing belts 110 andare coupled with the elastic strings 120. An anti-friction device 150mounted at the lower part of the elastic strings 120 to prevent frictionby sliding according to movement and positioning the strings at thelowest point of the strings and a handle coupler 131 are used to couplethe handle 130.

The first connecting rings 113 and the second connecting rings 114 areformed as closed rings. The first connecting means 121 and the secondconnecting means 122 are formed as rings that may be open and closed tobe coupled to or decoupled from the first connecting rings 113 and thesecond connecting rings 114.

The webbing belts 110 have shoulder pads 115 which are formed offlexible rubber or plastic and which allow the webbing belts 110 to bestably fastened onto the user's body with reduced friction on the user'sshoulders.

The detachable, ring-shaped first connecting means 121 and secondconnecting means 122, respectively, are provided at both ends of theelastic strings 120. Provided are covering means 123 to cover theelastic strings 120 which have elasticity. As illustrated, one coveringmeans 123 may be provided. Alternatively, a plurality of covering means123 may be provided and spaced apart from one another.

The covering means functions to prevent friction to the user's body whenthe elastic strings 120 extend or contract while preventing an accidentthat may occur when the elastic strings 120 are disconnected. In otherwords, the elastic strings 120 may impact and injure the user's body bytheir own elasticity. However, where an elastic string 120 isdisconnected, the elastic string 120 is first moved inside the coveringmeans 123 and, thus, the user may be prevented from injury.

The covering means is formed of an empty tube with a width enough toallow the elastic string 120 to freely travel back and forththereinside.

The elastic string 120 may be formed of one or more wires depending onthe strength of exercise. Where the elastic string 120 is formed of fourwires, there are provided larger rings (not shown) hung on the fourwires and a smaller ring (not shown) hung on two of the four wires.

The elastic strings 120 are detachably coupled at both ends thereof tothe webbing belts 110 so that the webbing belts 110 and (one pair of)left and right elastic strings 120 form closed loops. Thus, when a forceoccurs anywhere in the elastic string 120, the overall elastic string120 is tensioned and, when tension occurs at a side in the middle of theelastic string 120, the tension may be separated from where the tensionoccurs, and the first connecting ring and the second connecting ring ofthe webbing belts 110 are pulled and tensioned, Therefore, when the userswings to move up or down his arm so that the handle grabbed in the hand130 is moved, the handle coupler 131 coupled with the handle 130 istensioned from the handle 130, allowing the elastic string 120 to extendat the front and rear of the shoulder. The anti-friction device 150 ismounted at the lower part of the elastic strings 120 and slide accordingto the movement of the handle 130 to thereby prevent friction with thestrings and keeps the handle at the lowest point of the strings. Theanti-friction device 150 minimizes friction with the elastic strings 120and the handle coupler 131 and allows the handle to move to the lowestpoint along the elastic strings and, as the user exercises, the sameamount of tension is generated by the handle 130 at the front and backof the elastic strings 120. In other words, the same amount of tensionis generated on both (front and rear) sides of the elastic strings 120coupled to both sides of the anti-friction device 150.

The handle 130 is provided to be movable on the elastic strings 120between the covering means 123 and is connected to the ring-shapedhandle coupler 131 that may be open and closed.

The handle 130 is coupled, via the handle coupler 131, with theanti-friction device 150 that is mounted at the middle portion, i.e.,the lowest portion, of the elastic strings 120 to allow the elasticstrings to slip according to exercise, thereby preventing friction whilekeeping the elastic strings positioned at the lowest point, under thearmpit. Therefore, when the user pulls out the handle 130, the tensionapplied to the elastic strings 120 extending forward or backward of theuser's body may be evenly distributed.

At this time, the handle coupler 131 of the handle 130 is connected atthe user's armpit which is around the middle of the elastic string 120,allowing the handle 130 to be positioned at the lowest point of theelastic string 120.

The upper part of the handle 130 is connected to the elastic string 120via the handle coupler 131, and a waist string 140 is connected to thethird connecting ring 132, which is provided at the lower part of thehandle 130, via a waste coupler 141—as such, both the upper and lowerpart of the handle 130 are elastically connected.

The waist string 140, which is provided as a separate elastic stringfrom the elastic string 120 and passes the rear (waist or butt) of theuser, is connected to the third connecting rings 132 which are providedat lower parts of the left and right handles 130 on the user's body, sothat the muscles in the front of the upper arm and in the front of theshoulder are strongly tensioned when the arm moves from a lower and rearposition to an upper and front position. In other words, the handles 130are coupled at both sides of the waist string 140 and the elasticstrings 120, forming a second closed loop. According to the presentinvention, as the closed loop is formed without an opening between firstsides of the handles 130 and the elastic strings 120, when extension andflexion (or forth-and-back movement) with respect to the elbow joint isrepeated, the upper and lower parts and the front and rear of the armare simultaneously tensioned, leading to movement of the arm whenwalking.

When the user moves his arm from the back to front to flex the elbowjoint of the arm as shown in FIG. 9B, the waist string 140 is extended,producing tension and hence contracting biceps and deltoid andsupraspinatus. When the user extends his arm from the front to back asshown in FIG. 9A, the elastic strings 120 inside the covering means 123are extended to produce tension and hence contracting triceps. Suchflexion and relaxation leads to movement of the user's arm as the userwalks, thereby raising exercise effects.

The waist string 140 is formed of an elastic string with waist couplers141 formed at both ends thereof and is positioned on the user's waist orbutt.

The third connecting ring 132 may be formed of a closed triangular ring.The waist coupler 141 is formed of a plastic ring that may be open andclosed to be hooked to or unhooked from the third connecting ring 132.

The waist ring 140 may be covered with a covering means, as are theelastic strings 120, to be prevented from friction.

The waist ring 140 may be inserted through the loops of the pants,allowing the wearable arm exerciser to be stably worn.

The handles 130 are coupled with the elastic strings 120 and the waiststring 140, giving strong stimulation to the arms, and thus an exerciseeffect, when the user pulls the handles 130 from a rear to frontposition, from a front to rear position, from a lower to upper position,or from an upper to lower position. In other words, an exercise effectis achieved when the arm is moved backward, as well as forward, whilewalking.

When the handle 130 is moved down, the triceps may be strongly tensionedand, when the handle 130 is moved up, the biceps and deltoid may bestrongly tensioned.

The handle 130 may include a rear part 130 b and a front part 130 awhich is formed of a pad with a predetermined thickness and width andsurrounding the back of the hand when the rear part 130 b is grabbed bythe user. The user's hand may be inserted between the front part 130 aand the rear part 130 b and may thus be stably placed.

Such a structure of the handle 130 allows the user to hang his hand onthe handle 130 without tightly holding it when his arm feels fatigue.Thus, the user may relax and recover from fatigue.

In the wearable arm exerciser 100 usable while walking as describedabove, the user wears the wearable arm exerciser 100 by putting it onhis shoulders, with the webbing belts 110 and the elastic strings 120coupled together, adjusts the length to fit the user's body, and thenholds, in his hands, the handles 130 coupled to both sides of theelastic strings 120, which are placed on the user's chest and under thearmpits and alternately pulling the right and left handles 130 whilewalking to thereby do upper body exercise.

The armpits are depressed parts on the sides of the chest and under theshoulders, which contain lots of fat and a large sweat gland and lymphnode group under the skin and where major nerves and blood vessels pass,and is susceptible to adhesion in such a disease as frozen shoulder andhard to exercise. However, exercise on the wearable arm exerciser 100 ofthe present invention may prompt lymph circulation at or around thearmpits and increase the flexibility of the surrounding tissues.

On the other hand, as illustrated in FIG. 6, the anti-friction device150 may be provided between the handle coupler 131 and the elasticstrings 120 to generate the same amount of tension at the front and backof the strings by keeping the handle 130 positioned at the lowest pointof the strings while reducing continuous friction between the handlecoupler 131 and the elastic strings 120 due to changes in the positionof the handle 130, The anti-friction device 150 includes a circularstring support 153 that has a diameter large enough to enable wide linecontact to reduce frictional wear of the elastic strings 120 and ahandle fastener 151 which is coupled with the string support 153 andinto which the handle coupler 131 is fitted.

The string support 153 includes a string moving part 154 that isrecessed inward to allow the elastic strings 120 to be insertedtherethrough and prevent the elastic strings 120 from escaping off, astring fixing part 154 surrounding the elastic strings to prevent theelastic strings 120 from escaping off, around the handle fastener 151,and stepped portions 157 where the elastic strings 120 are exposed atthe ends of the string fixing part 154. The central portion of thestring support 153 has a hollow central hole 156, so that the elasticstrings 120 slip while making wide line contact in the string movingpart 154. The string fixing part 154 has a groove formed in the outsidethereof to allow the elastic strings 120 to be inserted therethrough.

The handle fastener 151 is shaped as a hollow circle or an ellipse andis coupled with the handle coupler 131. One hand fastener 151 may beprovided on one side of the groove 152 in the string support 153 asillustrated in FIG. 7 or two hand fasteners 151 may be provided on bothsides of the groove 152 in the string support 153 as illustrated in FIG.8.

The elastic strings 120 are inserted into the anti-friction device 150,and when the handle 130 moves back and forth, the elastic strings 120slip in the circular string fixing part 154 while making wide linecontact. Therefore, continuous friction to any one portion of theelastic strings 120 may be prevented, allowing for long-term use of theelastic strings 120. The anti-friction device 150 which has a slippingfunction may allow the strings to slip during exercise, keeping thehandle 130 positioned at the lowest point of the strings and henceallowing the same amount of tension to be distributed on the front andback strings of the user's body.

Further, the anti-friction device 150 may minimize friction between theelastic strings 120 and the handle coupler 131 while allowing thelimited elasticity of the elastic strings to be used as efficient aspossible. For example, if 100 g of tension is generated at the handle130 when the front elastic strings are pulled by 1 cm, then 200 g oftension is generated if the front and back strings are simultaneouslypulled by 1 cm, so that the load of exercise doubles.

Given the limited elasticity according to the length of the elasticstrings 120, if the same amount of tension is generated at the front andback strings, the efficiency of exercise may be significantly increased.

As such, the present invention allows the user to work or move, with itworn, and allows the user to easily exercise anytime as long as he has ashort break time.

Further, the present invention, by its excellent wearability andportability, allows the user to do exercise even when seated in the sameway as he can in other positions. In particular, while standing orsitting, the user may do exercise on the wearable arm exerciser, withhis left hand put in the right handle 130 or with his right hand put inthe right handle 130. This way enables exercise in various directionsand leads the user to exercise fitting the user's environment whilestimulating various upper body muscles.

Thus, according to the present invention, a wearable arm exerciser 100usable for walking includes, in its basic structure, webbing belts 110passing from a user's chest through the user's shoulders and crossed inan X shape, one or more elastic strings 120 coupled, in front or behind,to the webbing belts 110, and handles 130 coupled with the elasticstrings 120 to produce tension and further including a waist string 140which is connected to the handles 130 to exercise triceps, wherein, asthe elastic strings 120 and the waist string 140 are connected to theupper and lower parts, respectively, of the handles 130, the musclesaround the shoulder joints may be tensioned by back-and-forth movementand upper-and-lower movement of the arm that arise when the shoulderjoint moves while walking, thereby producing an exercise effect toreinforce the flexibility of shoulder muscles and preventing orrelieving shoulder disease.

Further, in the wearable arm exerciser 100 usable while walking,according to the present invention, the user may exercise the triceps bypulling down the elastic strings 120 ahead of the shoulders and may alsoexercise biceps, deltoid, and supraspinatus that are used when the armextends to move from a rear to front position or from a lower to upperposition.

Further, in a wearable arm exerciser 100 usable while walking, accordingto the present invention, the connecting means are connected to themiddles of the elastic strings 120, i.e., around the armpits so as toevenly distribute tension applied to the elastic strings 120 on thefront and rear of the user's body when the handles 130 are pulled, and aseparate elastic string, i.e., the waist string 140, is connected to theconnecting rings 132 provided under the handles 130 to pass over therear part (waist or butt) of the user's body to produce tension whosestrength is adjustable in the muscles in the front parts of the upperarm and shoulder when the arm is moved from a rear to front position orfrom a lower to upper position, thereby increasing the exercise effect.

Further, a wearable arm exerciser 100 usable while walking may be easilyproduced in a simplified structure including webbing belts 110 crossedin an X shape on the user's back, elastic strings 120 coupled with thewebbing belts 110, and handles 130 coupled to the elastic strings 120and a waist string 140 connected to the handles 130, in which as theuser couples the elastic strings 120 to the webbing belts 110 on theshoulders, wears the wearable arm exerciser 100, and repeatedly pullsthe handles 130 while walking, the wearable arm exerciser 100 enablessteady upper body exercise along with leg exercise.

Further, in a wearable arm exerciser 100 usable while walking, thestructure of the wearable arm exerciser 100 in which the left and rightelastic strings 120 are connected to the webbing belts 110 so thattension is delivered to the left elastic string 120 when the righthandle 130 is pulled enables a natural, simultaneous, and balancedposing of the same load of exercise to both arms during the course ofswinging the arm forward and backward, and after a predetermined degreeof tension is formed by pulling down the handle 130, back-and-forthmovement is performed, steadily delivering a predetermined degree ormore of tension to the arms during the course of exercise and hencegiving rise to increased physical endurance.

Further, according to the present invention, a wearable arm exerciser100 usable while walking is formed of an elastic material to be tightlyworn on the user's body so that it may be put on a dress suit ortraining suit, thus allowing the user to exercise during a spare time atwork or commuting or taking a walk.

Further, in the wearable arm exerciser 100 usable while walking, boththe handles 130 may be pulled in opposite directions, transferringtension to more muscles in a wider area.

Further, a wearable arm exerciser 100 usable while walking, according tothe present invention, may be worn while walking or jogging to enableupper body (muscles around the arms and shoulders) exercise in a naturalway and with the expectation of balanced development of upper and lowerbody muscles and the prevention or mitigation of various musculoskeletaldiseases from the shoulders through the elbow joints to the wrists.

Further, according to the present invention, a wearable arm exerciser100 usable while walking may be adjusted in length while being worn andbe easy to wear or remove.

Further, in a wearable arm exerciser 100 usable while walking, theelastic strings 120 formed of one or more wires may be separated by thecovering means 123, thereby preventing friction against the user's bodyand injury due to the elastic string 120 when disconnected.

Further, in a wearable arm exerciser 100 usable while walking, thestrength of exercise may be adjusted by varying the thickness of theelastic strings 120 coupled to the webbing belts 110 or the number ofthe elastic strings 120.
